1. A method of making carbon fibers, the method comprising:
spinning fibers comprising an esterified lignin composition, to give spun fibers, the esterified lignin composition comprising
lignin comprising at least one esterified —OH group, wherein the esterified —OH group has the structure —OC(O)R, wherein each R is independently a C1-C30 hydrocarbyl group, andpoly(lactic acid); and heating the spun fibers to obtain the carbon fibers.
